Final answer:
True, the Extrude Command in CAD is a tool for creating 3D objects by extending a 2D sketch or face along a linear path. It is a fundamental process in transforming plans into dimensional models in engineering and design.
Step-by-step explanation:
The statement is true. The Extrude Command is a feature commonly used in Computer-Aided Design (CAD) programs that creates 3D geometry by extending a 2D sketch or face along a specified linear path. This function is essential for turning flat sketches into 3D models in various fields of engineering and design.
When using the extrude tool, you would select a 2D sketch or planar face, then choose the direction and distance you want to extrude it. This could be a simple straight extrusion or one that includes tapering or other complex operations depending on the capabilities of the CAD software you're using.
For example, if you're designing a simple cylinder, you'd draw a circle as your 2D sketch, and then use the extrude command to pull that circle into a third dimension, creating the cylindrical shape by specifying the length of the extrusion. This demonstrates how the tool transitions a shape from a 2D to a 3D object by adding depth.
